More information can be found at `Cavium, Inc Official Website `_. Features -------- Features of the OCTEON TX FPAVF PMD are: - 32 SR-IOV Virtual functions - 32 Pools - HW mempool manager Supported OCTEON TX SoCs ------------------------ - CN83xx Prerequisites ------------- See :doc: `../platform/octeontx.rst` for setup information. Pre-Installation Configuration ------------------------------ Config File Options ~~~~~~~~~~~~~~~~~~~ The following option can be modified in the ``config/rte_config.h`` file. Please note that enabling debugging options may affect system performance. - ``RTE_MBUF_DEFAULT_MEMPOOL_OPS`` ( set to ``octeontx_fpavf``) Set default mempool ops to octeontx_fpavf. Driver Compilation ~~~~~~~~~~~~~~~~~~ See :doc:`../linux_gsg/build_dpdk` for more information on compiling DPDK. Initialization -------------- The OCTEON TX fpavf mempool initialization similar to other mempool drivers like ring. However user need to pass --base-virtaddr as command line input to application example test_mempool.c application. Example: .. code-block:: console .//app/test/dpdk-test -c 0xf --base-virtaddr=0x100000000000 \ --mbuf-pool-ops-name="octeontx_fpavf"
